Col. Ted Westhusing, a West Point scholar, put a bullet in his head in Iraq after reporting widespread corruption. His suicide note -- complaining about human rights abuses and other crimes -- was addressed to his two commanders, including Gen. David Petraeus, now leader of the U.S. "surge" effort in Iraq. It urged them to "Reevaluate yourselves....You are not what you think you are and I know it."
